Measurement uncertainty specifications are based on a matched DUT, RBW = 100 Hz, RF attenuation = 10 dB,
nominal source power = 0 dBm, +20 °C to +30 °C
300 kHz ≤ f ≤ 50 MHz
0 dB ≤ insertion loss < 40 dB nominal < 2°
50 MHz < f ≤ 3.6 GHz
0 dB ≤ insertion loss < 50 dB nominal < 2°
50 dB ≤ insertion loss < 70 dB nominal < 3°
3.6 GHz < f < 6 GHz (R&S ® FSH8 only)
0 dB ≤ insertion loss < 50 dB nominal < 2°
